Description

Technical Field

[0001] This invention relates to the field of spinning machine technology, specifically to a self-detecting spinning machine and its leaf spring cradle structure. Background Technology

[0002] The self-testing spinning frame is a spinning equipment that integrates online monitoring and intelligent diagnostic functions. It can detect yarn breakage, abnormal tension, and other working conditions in real time and automatically alarm. Its leaf spring cradle structure uses leaf springs as elastic pressure components, which, together with the cradle body and locking mechanism, provide stable pressure to the drafting rollers. The structure is simple, the pressure is uniform, and the spinning stability and equipment reliability are improved.

[0003] In traditional ring spinning machines, the spindle rotates to wind the yarn. However, in actual production, after one winding and unloading is completed, the spindle continues to rotate due to inertia, causing a small amount of tail yarn to remain attached to the spindle. If these tail yarns are not cleaned in time, they will gradually accumulate and entangle, affecting the normal start of the next production run and causing inconvenience to operation. Manual intervention is often required to remove them, but due to the large number of spindles, manual cleaning is not only time-consuming and labor-intensive, but also difficult to completely remove all tail yarns, thus reducing the overall performance of the ring spinning machine. Summary of the Invention

[0012] Beneficial effects The technical solution provided by this invention has the following advantages compared with the known prior art: I. This invention, by setting up components such as an energy storage cleaning mechanism, transmits the roller power synchronously to the reciprocating screw through the meshing of the transmission gear and the driven gear, driving the reciprocating screw sleeve to move the extrusion plate back and forth. When the extrusion plate moves, the sealing box and the one-way air valve cooperate to create a negative pressure in the movable groove, which pulls the cleaning plate into the movable groove. When the ring plate moves to the bottom due to machine stop, it pushes the support plate down, and the cleaning plate pops out under the action of the connecting spring. It moves with the extrusion plate to scrape and clean the tail yarn on the surface of the spindle rod. Thus, it achieves the effect of automatically removing the tail yarn of the spindle rod without manual intervention, avoiding the tail yarn from getting tangled and affecting subsequent production. It significantly reduces the labor intensity of manual cleaning and improves the continuity of equipment operation and the thoroughness of cleaning.

[0013] II. This invention, through the inclusion of components such as a negative pressure adjustment assembly, allows the sealing ring to move with the reciprocating screw sleeve, adjusting and sealing the adsorption ports on the surface of the suction tube. This opens some adsorption ports while closing others, achieving a localized enhancement of adsorption strength without changing the total adsorption force. Simultaneously, when the yarn breaks, the steel ring of the ring plate stops rotating, the touch block resets, triggering the touch switch to energize the electromagnetic block. The electromagnetic block then magnetically connects with the moving ring, causing the sealing ring to slide along the suction tube to precisely open the adsorption port corresponding to the yarn breakage point. This concentrates the negative pressure on the yarn breakage location to enhance suction and prevent the broken yarn from scattering and tangling. This mechanism simultaneously performs real-time detection of yarn breakage, precise adjustment of the adsorption port, and self-cleaning and unclogging of the suction tube, significantly improving the efficiency of fly waste collection and the cleanliness of the spinning environment, ensuring the stability and continuity of equipment operation.

[0014] Third, this invention, by setting up components such as a movable cleaning assembly, uses the rotation of a driven gear to drive a push block to intermittently push a moving block, causing the push ring to rotate intermittently. This, in conjunction with a cleaning scraper, cleans the roller surface, while a cleaning brush rolls and sweeps the leather roller, causing impurities to fall into a collection box. When the sealing ring moves to a designated position, the support block pushes the connecting block to align with the connecting groove. Under negative pressure, impurities in the collection box flow through a hose into the suction tube for centralized processing. This achieves coordinated cleaning of the roller, leather roller, and suction tube, as well as sealed collection of impurities, preventing secondary spillage of impurities and ensuring stable drafting accuracy and spinning quality.

[0015] Fourth, this invention sets up a bracket, a leaf spring, and a roller gripper. The leaf spring is welded to the roller gripper at its front end. The welded structure ensures the connection strength and rigidity, ensuring the stable transmission of the pressure force, providing uniform and stable drafting pressure to the roller, improving the yarn drafting uniformity and spinning quality, simplifying the assembly process, and reducing maintenance costs.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] The present invention will be further described below with reference to embodiments.

[0021] See attached document Figure 1-15 A self-detecting spinning frame includes: a spinning frame body 1, with three sets of rollers connected to one side of the spinning frame body 1 via a transmission rod, the three sets of rollers being rotatably connected to the interior of the spinning frame body 1, suction tubes at the bottom of the three sets of rollers being connected to a negative pressure device of the spinning frame body 1, and a ring rail being connected to the interior of the spinning frame body 1. The frame also includes: an energy storage cleaning mechanism 2 for cleaning the spindle rods, the energy storage cleaning mechanism 2 including a transmission gear 201, and the transmission gear... 201 is fixedly connected to the transmission rod of the front roller. A driven gear 202 meshes with one side of the transmission gear 201. Two sets of reciprocating screws 203 are provided on one side of the driven gear 202, and a sliding rod is slidably connected between the two sets of reciprocating screws 203 via a push spring. One set of reciprocating screws 203 is rotatably connected to the spinning frame body 1. Reciprocating screw sleeves 204 are threaded onto the surfaces of both sets of reciprocating screws 203. A negative screw is provided on one side of the reciprocating screw sleeve 204. The pressure regulating component 205 has a reciprocating screw sleeve 204 with a pressing plate 206 fixedly connected to the bottom. A movable groove is provided on one side of the pressing plate 206, and a one-way air valve 207 is connected to one side of the movable groove. A cleaning plate 208 is slidably connected inside the movable groove, and the cleaning plate 208 is elastically connected to the movable groove through a connecting spring. A sealing block 209 is slidably connected to the bottom of the movable groove, and the sealing block 209 is slidably connected to the bottom of the pressing plate 206. A support plate 210 is slidably connected to the bottom of the sealing block 209, and the support plate 210 is located at the bottom of the ring rail. The support plate 210 is elastically connected to the spinning machine body 1 through a support spring. A sealing box 211 is slidably connected to the outside of the pressing plate 206, and the sealing box 211 is fixedly connected to the spinning machine body 1. A negative pressure box 212 is connected to one side of the sealing box 211 through a one-way cleaning valve, and the inside of the negative pressure box 212 is slidably connected to the pressing plate 206. A movable cleaning component 213 is provided on the top of the negative pressure box 212. The transmission gear 201 is fixedly connected to the transmission rod of the front roller, allowing direct reuse of the original roller's transmission power without the need for an additional independent drive source, effectively reducing equipment modification costs and operating energy consumption. The driven gear 202 meshes with the transmission gear 201, synchronously transmitting the rotational power of the transmission rod to the reciprocating screw 203, achieving synchronized power linkage and ensuring precise matching of the cleaning action with the spinning process of the spinning machine. A sliding rod is slidably connected between the two sets of reciprocating screws 203 via a push spring, flexibly adapting to the movement stroke of the reciprocating screw sleeve 204. One set of reciprocating screws 203 is rotatably connected to the spinning machine body 1, ensuring the transmission stability of the reciprocating screws 203. Simultaneously, the elasticity of the push spring enables the two sets of reciprocating screws 203 to move. The position between them is adaptively adjusted; the reciprocating sleeve 204 is threadedly engaged with the reciprocating screw 203, which can convert the rotational motion of the reciprocating screw 203 into linear reciprocating motion, thereby driving the extrusion plate 206 and the negative pressure adjustment component 205 to move synchronously, realizing the continuous reciprocating execution of the cleaning action; a movable groove is opened on one side of the extrusion plate 206, which can provide sliding limit space for the cleaning plate 208. A one-way air outlet valve 207 is connected to one side of the movable groove. The one-way air outlet valve 207 has a one-way guiding direction from the inner cavity of the movable groove to the inner cavity of the sealing box 211, allowing gas to flow unidirectionally from the movable groove to the sealing box 211, and is blocked in the reverse direction. During the movement of the extrusion plate 206, it can cooperate with the sealing box 211 to extract the gas in the movable groove, so that the cleaning plate 208 is squeezed continuously under the action of negative pressure. The spring is connected and retracted into the movable groove; a sealing block 209 is provided at the bottom of the movable groove to seal the bottom of the movable groove and ensure the stability of the air pressure in the movable groove. The sealing block 209 is slidably connected to the bottom of the extrusion plate 206, and can achieve adaptive sliding adjustment in conjunction with the movement of the extrusion plate 206; the support plate 210 is located at the bottom of the ring rail and is elastically connected to the spinning machine body 1 through the support spring, which can form a stable support for the sealing block 209. During the movement of the sealing block 209, it can slide along the support plate 210. At the same time, the support plate 210 can adapt to the lifting and lowering movement of the ring rail through the elastic force of the support spring. When the ring rail moves to the bottom, it means that the device stops. The support plate 210 can be pushed to squeeze the support spring and drive the sealing block 209 out of the bottom of the movable groove. When external gas enters the movable slot, the cleaning plate 208, freed from negative pressure constraint, is ejected by the elastic force of the connecting spring. Moving with the squeezing plate 206, it scrapes and cleans the tail yarn on the surface of the spindle rod, fundamentally solving the problem of tail yarn accumulation and entanglement on the spindle rod surface. This eliminates the need for manual cleaning, significantly reducing labor intensity while ensuring the comprehensiveness and thoroughness of spindle rod cleaning. The cleaning plate 208 pushes impurities to the inlet of the negative pressure box 212, and then the connecting valve 2058 opens. Under the negative pressure inside the negative pressure box 212, the impurities are drawn into the interior of the negative pressure box 212. The one-way cleaning valve allows gas to flow unidirectionally from the inner cavity of the sealed box 211 to the inner cavity of the negative pressure box 212, and blocks flow in the opposite direction. The outer side of the extrusion plate 206 is slidably connected to the sealing box 211 fixed on the spinning machine body 1, forming a sealed cavity with the sealing box 211. During the reciprocating movement of the extrusion plate 206, negative pressure suction is generated through changes in the cavity volume. The sealing box 211 is connected to the negative pressure box 212 via a one-way cleaning valve, allowing gas from the sealing box 211 to be transported to the inside of the negative pressure box 212. When the sealing box 211 forms a negative pressure, the gas in the movable slot can be extracted through the one-way exhaust valve 207, allowing the movable slot to quickly enter a negative pressure state. Simultaneously, the one-way cleaning valve prevents airflow backflow, ensuring the continuous and stable negative pressure suction. The negative pressure box 212, in conjunction with the negative pressure regulating component 205, can adsorb and collect the tail yarn and fly waste scraped off by the cleaning plate 208, preventing the cleaned impurities from scattering inside the equipment or onto the yarn surface, thus preventing contamination. The quality of the yarn is negatively affected by the quality of the spinning process. Simultaneously, the reciprocating sleeve 204 moves to achieve full-stroke cleaning and collection. It can also work in conjunction with the moving cleaning component 213 to periodically clean the rollers and lead rollers, expanding the equipment's cleaning coverage. The suction tube at the bottom of the rollers is connected to the negative pressure device of the spinning machine, which can adsorb and collect fly ash and broken yarn generated during spinning. Combined with the negative pressure adjustment component 205, it achieves adaptive adjustment of the negative pressure of the suction tube, further improving the fly ash collection effect and preventing fly ash from affecting the spinning environment and stable equipment operation. The ring rail is powered by the spinning machine body 1, driving the traveler to complete the yarn winding action. It also provides the basis for triggering the negative pressure adjustment component 205, ensuring that the cleaning action, negative pressure adjustment action, and winding process are executed synchronously, achieving coordinated linkage of all processes within the equipment. One side of the reciprocating sleeve 204 is provided with a reset delay post 3. The delay end of the reset delay post 3 is fixedly connected to a connecting rod 4, and the connecting rod 4 is fixedly connected to a slide rod. The reset delay post 3 is slidably connected to the reciprocating sleeve 204, which can limit and delay the reset stroke of the reciprocating sleeve 204. When the reciprocating sleeve 204 moves to contact the reset delay post 3 and drives it to move synchronously, the reset delay post 3 can drive the reciprocating screw 203 on the side away from the connecting rod 4 to move synchronously through the connecting rod 4. Since the two sets of reciprocating screws 203 are slidably connected through the slide rod, the reciprocating screw 203... The movement can temporarily separate the driven gear 202 from the transmission gear 201, causing the reciprocating screw sleeve 204 to stop its reset action after losing its rotational driving force. This allows for a brief pause in the cleaning mechanism, providing sufficient time for cleaning and collecting the tail yarn on the spindle rod surface, ensuring the comprehensiveness and thoroughness of the tail yarn cleaning. The reset action can also be started and stopped through a purely mechanical structure, eliminating the need for additional electrical control components, simplifying the equipment's control logic, and further improving the stability and reliability of the mechanism's operation. Additionally, the sealing ring 2051 can increase the adjustment and switching time for adjusting the opening and closing of the cotton suction port of the suction tube. See attached document Figure 1-10The negative pressure regulating component 205 is used to adjust the opening and closing of the suction port of the suction tube, enhance the local negative pressure suction force, and dynamically open according to the yarn breakage signal. It includes a sealing ring 2051, which is slidably connected to the surface of the suction tube and connected to the negative pressure box 212 via a hose and a one-way delivery valve. A movable ring 2052 is fixedly connected to one side of the sealing ring 2051, and a movable column 2053 is slidably connected to the surface of the movable ring 2052. The movable column 2053 is fixedly connected to a reciprocating screw sleeve 204, and an electromagnetic block 2054 is fixedly connected inside the movable column 2053. The electromagnetic block 2054 is magnetically connected to the movable ring 2052 and elastically connected to the movable ring 2052 via a pressing and resetting column. The electromagnetic block 2054 is electrically connected to a touch switch via a wire. 2055, and the touch switch 2055 is fixedly connected to the inside of the steel ring plate. The top of the touch switch 2055 is provided with a touch block 2056, and the touch block 2056 is fixedly connected to the inside of the steel ring plate through a return spring (the return spring is not shown in the figure). An inclined block 2057 is slidably connected to one side of the touch block 2056, and the inclined block 2057 is fixedly connected to the steel wire ring of the steel ring plate. The touch switch 2055 is electrically connected to a connecting valve 2058 through a wire, and the connecting valve 2058 is connected to the negative pressure box 212. The one-way conveying valve is connected to the negative pressure box 212. The one-way conveying valve has a one-way flow direction from the inner cavity of the negative pressure box 212 to the inner cavity of the sealing ring 2051. It only allows gas and impurities to flow unidirectionally from the inside of the negative pressure box 212 to the inside of the sealing ring 2051, and cuts off in the reverse direction. The connecting valve 2058 is prior art. The tilting block 2057 is fixedly connected to the wire ring of the ring rail and can rotate synchronously with the wire ring. During normal spinning, it continuously pushes the contact block 2056 upward, preventing the contact block 2056 from triggering the touch switch 2055. When a yarn breakage occurs, the wire ring stops rotating, and the tilting block 2057 can no longer push the contact block 2056. The touch switch 2055 is existing technology. The contact block 2056 resets under the action of the return spring and triggers the touch switch 2055, realizing real-time self-detection of yarn breakage without the need for manual real-time monitoring, greatly improving the intelligence level and spinning continuity of the spinning machine; the contact... Switch 2055 is electrically connected to electromagnetic block 2054 via wires. Electromagnetic block 2054 is existing technology. The touch switch 2055, fixed inside the steel collar plate, can precisely control the start and stop of electromagnetic block 2054 through its own on / off switching, realizing automatic triggering and synchronous response of electromagnetic block 2054's action. Electromagnetic block 2054 is fixedly installed inside moving column 2053. Moving column 2053 is fixedly connected to reciprocating screw sleeve 204 and can move synchronously with reciprocating screw sleeve 204, providing a stable installation base for the cooperation of electromagnetic block 2054 and moving ring 2052. When electromagnetic block 2054 is energized, it can generate magnetic attraction. A movable ring 2052, magnetically connected to the top of the sealing ring 2051, drives the movable ring 2052 to move synchronously with the sealing ring 2051, thereby controlling the sliding motion of the sealing ring 2051 and actively adjusting the negative pressure of the suction tube. The sealing ring 2051 is slidably connected to the surface of the suction tube, and can change the on / off state of the suction tube's suction port through its own sliding, thereby achieving adaptive adjustment of the suction force of the suction tube's negative pressure. When some suction ports are closed, the suction force of the remaining suction ports can be significantly enhanced without changing the total suction force. This specifically improves the adsorption effect of broken yarn and fly waste when yarn breaks, preventing broken yarn from drifting away. Scattered entanglement causes equipment failure; the sealing ring 2051 is connected to the negative pressure box 212 through a hose and a one-way conveying valve, which can stably transport the gas and impurities collected in the negative pressure box 212 to the sealing ring 2051, and finally flow into the cotton suction pipe for centralized treatment. At the same time, the one-way conveying valve can effectively prevent the airflow and impurities in the cotton suction pipe from flowing back into the negative pressure box 212, ensuring the stability and sealing of impurity collection and transportation, preventing the cleaned impurities from scattering again and affecting the spinning quality, and triggering the switch will open the connecting valve 2058. When the connecting valve 2058 is open, the impurities generated by the broken end can be collected under its negative pressure. The sealing ring 2051 has a scraper ring 5 fixedly connected to one side, and a protrusion 6 slidably connected to the inner side of the scraper ring 5. The bottom of the protrusion 6 is inclined, and the top of the protrusion 6 is elastically connected to the scraper ring 5 by pushing a reset post. The scraper ring 5 is fixedly connected to the outer side of the sealing ring 2051 and can slide synchronously with the sealing ring 2051 to continuously scrape the surface of the suction tube, removing cotton fibers and impurities adsorbed on the surface of the suction tube, and ensuring smooth airflow at the suction port of the suction tube. The protrusion 6 is elastically connected to the scraper ring 5 by pushing a reset post, which allows for the extension and retraction of the protrusion 6. It provides stable elastic support and reset driving force; the protrusion 6 is slidably connected to the inner side of the scraper ring 5 and is inclined at the bottom. During the sliding process of the scraper ring 5, it can achieve adaptive extension and retraction by contacting the suction port of the suction tube with its own inclined surface, pushing and clearing the impurities blocking the suction port. At the same time, under the continuous movement of the sealing ring 2051, it can easily move out of the suction port of the suction tube with its own inclined structure, realizing the synchronous cleaning of the surface of the suction tube and the inside of the suction port, further avoiding the clogging of the suction port of the suction tube, and improving the suction stability of the suction tube and the comprehensiveness of impurity cleaning. See attached document Figure 1-13 The movable cleaning component 213 moves with the reciprocating screw sleeve 204 to scrape and brush the surfaces of the rollers and leather rollers, and collects impurities in a sealed manner into the suction tube for centralized processing under negative pressure. It includes a collection box 2131, which is fixedly connected to the reciprocating screw sleeve 204. A cleaning scraper 2132 is slidably connected to the top of the collection box 2131 and elastically connected to the collection box 2131 via a movable spring. A push ring 2133 is provided on one side of the cleaning scraper 2132, and one side of the push ring 2133 is rotatably connected to the collection box 2131. A moving block 2134 is fixedly connected to one side of the push ring 2133. A push block 2135 is provided, and the push block 2135 is fixedly connected to the driven gear 202. A cleaning brush 2136 is detachably connected to the top of the collection box 2131. The bottom of the cleaning brush 2136 is connected to the collection box 2131. A connecting block 2137 is connected to the bottom of the collection box 2131 through a hose. The connecting block 2137 is slidably connected to the sealing ring 2051. The connecting block 2137 is elastically connected to the sealing ring 2051 through a reset telescopic post. A connecting groove is provided on one side of the connecting block 2137, and the connecting groove is opened on one side of the sealing ring 2051. A support block 2138 is provided on the other side of the connecting block 2137, and the support block 2138 is fixedly connected to the suction tube. The collection box 2131 is fixedly connected to the reciprocating sleeve 204 and can move back and forth synchronously with the reciprocating sleeve 204, providing a stable installation base and a sealed impurity containment space for the cleaning collection components. The cleaning scraper 2132 is elastically connected to the collection box 2131 via a movable spring. Under the elastic force of the movable spring, it can precisely scrape the roller surface when it moves to a designated position with the collection box 2131, removing lint and fly waste adhering to the roller surface and preventing impurity accumulation from affecting the roller's drafting accuracy. A cleaning brush 2136 is detachably connected to the top of the collection box 2131. The cleaning brush 2136 can roll and brush the surface of the roller to thoroughly remove impurities. The cotton lint and impurities adhering to the roller surface ensure the uniformity of yarn drafting and the stability of spinning quality. The bottom of the cleaning brush 2136 is connected to the collection box 2131, allowing the impurities swept off by the brush to be directly sent into the collection box 2131 for centralized collection, preventing the impurities from being scattered again after cleaning and polluting the spinning environment. The push ring 2133 is rotatably connected to the collection box 2131. The movable block 2134 fixed on one side of the push ring 2133 can cooperate with the push block 2135 on the driven gear 202. With the rotational power of the driven gear 202, the push block 2135 intermittently pushes the movable block 2134, causing the push ring 2133 to rotate intermittently, without the need for an additional independent drive. The power source simplifies the equipment structure and can be used in conjunction with a negative pressure environment to achieve efficient collection of cleaning impurities. The collection box 2131 is connected to the connecting block 2137 via a flexible hose. The connecting block 2137 is slidably connected to the sealing ring 2051, which can create a stable negative pressure state inside the collection box 2131, enhance the adsorption and collection effect of impurities, and prevent impurities from scattering. The connecting block 2137 is elastically connected to the sealing ring 2051 via a reset telescopic column. One side of the sealing ring 2051 has a connecting groove adapted to the connecting block 2137. The suction tube is fixedly connected to a support block 2138 corresponding to the connecting block 2137. When the connecting block 2137 moves with the sealing ring 2051 to the... When in the designated position, the support block 2138 can squeeze and push the connecting block 2137, so that the connecting block 2137 is precisely aligned and connected with the connecting groove. At this time, the cleaning scraper 2132 and the cleaning brush 2136 will clean the roller and the leather roller respectively. The impurities collected in the collection box 2131 are transported to the sealing ring 2051 by negative pressure suction, and finally flow into the suction tube for centralized treatment, realizing the closed collection of impurities throughout the entire process. When the connecting block 2137 is released from the squeezing of the support block 2138, it can automatically reset under the elastic force of the reset telescopic column, disconnecting the passage with the connecting groove, avoiding the dispersion of the negative pressure suction of the suction tube, and ensuring the continuous and stable core adsorption effect of the suction tube. The push ring 2133 has a magnetic block 7 magnetically connected to one side, and the magnetic block 7 is fixedly connected to the inside of the collection box 2131. A stop block 8 is provided on one side of the magnetic block 7, and the stop block 8 is slidably connected to the collection box 2131. The stop block 8 is also elastically connected to the collection box 2131 via a reset support post. The magnetic block 7, fixedly connected to the inside of the collection box 2131, forms a magnetic connection with the push ring 2133, precisely limiting and fixing the rotational position of the push ring 2133. This ensures that the push ring 2133 remains stable in the non-push state, preventing it from rotating arbitrarily and affecting the cleaning effect of the cleaning scraper 2132, thus ensuring the stability and consistency of the cleaning operation. The stop block 8 is slidably connected to the collection box 2131, which can limit and block the rotation stroke of the push ring 2133. It can achieve precise limiting within the effective rotation range of the push ring 2133. When the rotational force of the push ring 2133 reaches a preset level, it can push the stop block 8 to make way and continue rotating. The stop block 8 is elastically connected to the collection box 2131 through the reset support column. It can achieve adaptive extension and retraction under the squeezing action of the push ring 2133, and at the same time provide a continuous and stable reset driving force for the stop block 8, ensuring that the stop block 8 can always form a stable limit and block on the push ring 2133, further improving the smoothness of the operation of the push ring 2133 and the overall operational reliability of the equipment. It is worth noting that although there are three sets of rollers and leather rollers, in actual use, this embodiment only sets up a cleaning structure for the set of rollers and leather rollers with the most impurities and the most frequent cleaning. The cleaning of other sets can be achieved by adding the same or similar cleaning structures according to actual needs to solve the corresponding cleaning problems. This technical solution does not limit this. It is worth noting that, to ensure the stability and energy transmission efficiency of the negative pressure system, all gas flow path connections in this technical solution are sealed with reliable sealing structures to form a dynamic or static sealing system, effectively preventing gas leakage. The specific selection of elastic elements such as springs and other key components should be adapted according to actual working conditions (such as pressure, frequency, load, etc.), and corresponding components or structures can be replaced or adjusted according to specific usage requirements to meet the performance requirements of long-term stable operation. The sliding and movement of each moving part are achieved through reasonable limiting and guiding structures in the existing technology (not fully shown in the figure) to ensure the coordinated function and reliable operation of each mechanism. In addition, conventional protection or additional limiting structures can be added to relevant components according to specific usage environment and requirements. The threshold parameters involved in this technical solution, such as the triggering conditions of the touch switch 2055 and the delay time of the reset delay column 3, can be adjusted according to actual usage requirements to adapt to different working conditions. The circuit control part involved in this technical solution is not specifically shown in the figure. Its implementation method is a conventional technical means in the field, which can be implemented by those skilled in the art based on the existing technology, and there is no need to elaborate.

[0022] See attached document Figure 1-15 A leaf spring cradle structure for a self-testing spinning frame includes a bracket 9, a leaf spring 10, and a roller gripping seat 11. The bracket 9 is adjustablely connected to the leaf spring 10, and the front end of the leaf spring 10 is welded to the roller gripping seat 11. The bracket 9 provides a stable mounting support for the leaf spring 10 and, being adjustable, allows for flexible adjustment of the pressure angle and preload of the leaf spring 10 according to spinning process requirements, adapting to the drafting and pressure requirements of different yarn types and improving the equipment's process adaptability. The welded connection between the front end of the leaf spring 10 and the roller gripping seat 11 ensures... The connection strength and structural rigidity between the leaf spring 10 and the roller gripper 11 prevent loosening during use, ensuring stable transmission of the pressure force and providing uniform and stable drafting pressure for the roller. This improves the uniformity of yarn drafting and spinning quality. Simultaneously, the welded connection simplifies the assembly process, reduces the number of connecting parts, and lowers the assembly difficulty and maintenance costs of the equipment. Welding makes the leaf spring 10 and the roller gripper 11 form an integral structure with no gaps or relative movement at the connection point, avoiding the loosening or fatigue that may occur with riveting due to long-term vibration. The welded structure significantly improves connection strength and fatigue resistance, ensuring stable transmission of pressure. The elastic pressure of the leaf spring 10 can act evenly and continuously on the roller, avoiding pressure fluctuations caused by loose connections. This improves the uniformity of yarn drafting and the stability of spinning quality. Welding eliminates the use of rivets, bolts, and other connectors, reducing the number of parts and assembly steps, and simplifying the assembly process of the cradle structure. At the same time, since the welded structure does not require regular tightening or replacement of connectors, it reduces the frequency and cost of equipment maintenance. During operation, the cradle of the self-testing spinning frame 1 is subjected to high-frequency vibration and continuous pressure. The welded connection provides excellent rigid support, ensuring that the leaf spring 10 and the roller grip 11 maintain a precise relative position during long-term operation, avoiding pressure failure caused by connection deformation. Compared with riveting, the welded connection has significant improvements in strength, stability, assembly efficiency, and maintainability, better meeting the requirements of the self-testing spinning frame 1 for the cradle structure of "uniform pressure, reliable operation, and convenient maintenance." It is an important improvement point for enhancing the overall performance of the equipment.

[0023] Working principle: During use, the self-detecting spinning frame body 1 starts and enters the spinning state. The matching leaf spring cradle structure is fixedly installed through the bracket 9. The adjustable leaf spring 10 evenly transmits the stable pressure force to the roller through the welded roller gripping seat 11, providing stable support for yarn drafting. The transmission rod inside the spinning frame body 1 drives the three sets of rollers to rotate synchronously to complete the yarn drafting operation. At the same time, it drives the transmission gear 201 fixed on its surface to rotate synchronously. The transmission gear 201 drives the driven gear 202 to rotate synchronously through meshing transmission, and then transmits the power to the two sets of reciprocating screws 203, so that the reciprocating screws rotate synchronously. The screw 203 drives the reciprocating sleeve 204 with the threaded connection on the surface to perform continuous linear reciprocating motion. During the movement of the reciprocating sleeve 204, the extrusion plate 206, the negative pressure adjustment component 205 and the collection box 2131 are moved synchronously, providing a continuous and stable power input for the cleaning operation and negative pressure adjustment of the whole machine. At the same time, the ring rail inside the spinning machine body 1 moves up and down according to the spinning process requirements, driving the wire traveler to rotate to complete the yarn winding operation. The suction tubes at the bottom of the three sets of rollers are connected to the negative pressure device of the spinning machine body 1, continuously generating adsorption force to perform basic adsorption and collection of fly and broken yarn generated during the spinning process. During the entire normal spinning process, the reciprocating sleeve 204 drives the extrusion plate 206 to continuously reciprocate within the sealed box 211 fixed to the spinning machine body 1. The extrusion plate 206 and the sealed box 211 cooperate to form a sealed cavity. The change in the cavity volume generates negative pressure suction, which continuously draws gas from the movable groove on the extrusion plate 206 through the one-way exhaust valve 207, creating a stable negative pressure state within the movable groove. Under the action of negative pressure, the cleaning plate 208 inside the movable groove squeezes the connecting spring and retracts into the movable groove to complete energy storage, preparing for subsequent spindle cleaning operations. After the yarn winding operation is completed and the equipment stops, the ring rail moves down to the bottom of its stroke. At this time, the roller still has some power and generates tailings. The ring rail pushes the support plate 210 to squeeze the support spring downwards, which in turn drives the sealing block 209 to slide along the bottom of the extrusion plate 206 and move out of the bottom of the movable groove, so that the movable groove is connected to the external environment and loses the negative pressure constraint. The cleaning plate 208 pops out quickly under the elastic force of the connecting spring and moves synchronously with the extrusion plate 206 driven by the reciprocating screw sleeve 204, thoroughly scraping and cleaning the tailings attached to the surface of the spindle rod. It can be completely removed without manual intervention. The method addresses the issue of yarn accumulation and tangling on the spindle surface, which is time-consuming, labor-intensive, and incompletely cleaned manually in the prior art. Simultaneously, when the reciprocating sleeve 204 moves to the end of its reset stroke, it contacts the reset delay post 3 and causes it to move synchronously. The reset delay post 3, through the connecting rod 4, drives the corresponding reciprocating screw 203 to move synchronously, temporarily separating the driven gear 202 from the transmission gear 201. The reciprocating sleeve 204 stops its reset action after losing its rotational driving force, allowing sufficient time for cleaning and collecting the spindle yarn, ensuring a thorough and complete cleaning effect. The swept-off yarn and impurities are collected under the negative pressure suction of the negative pressure box 212 and finally flow into the suction tube for centralized processing. To adapt to cleaning needs under different working conditions, the cleaning plate 208 can be adjusted according to the actual situation, so as to better complete the yarn scraping operation when moving laterally. It is worth noting that if the cleaning plate 208 is in the reset phase when it is moved out, that is, when it moves away from the negative pressure box 212, the negative pressure attraction generated by the negative pressure box 212 will also attract and collect the impurities. At the same time, the delay time of the reset delay column 3 can be adjusted according to actual usage requirements. During normal spinning, the reciprocating sleeve 204 continuously reciprocates, simultaneously driving the moving column 2053 to move synchronously back and forth along the axial direction of the suction tube. The moving column 2053 drives the sealing ring 2051 to continuously slide along the surface of the suction tube, alternately closing and opening the suction ports on the suction tube. Under the premise that the total suction force of the negative pressure device remains unchanged, by reducing the number of suction ports that are opened at the same time, the negative pressure suction force of a single open suction port is enhanced, thereby improving the adsorption and collection effect of fly waste and broken yarn during spinning. During the sliding of the sealing ring 2051, the scraper ring 5 fixed on its outer side slides synchronously along the surface of the suction tube, continuously scraping and cleaning the cotton lint and impurities attached to the surface of the suction tube. The protrusion 6 on the inner side of the scraper ring 5 can adaptively extend and retract during the sliding process, pushing and clearing the blockage impurities inside the suction port of the suction tube, avoiding blockage of the suction port and affecting the adsorption effect. At the same time, during normal spinning... During the spinning process, the ring rail continuously moves up and down according to the spinning process. During normal spinning, the wire ring on the ring rail rotates continuously as the yarn winds around, causing the tilting block 2057 to rotate synchronously and continuously push the contact block 2056 upward, so that the contact block 2056 will not trigger the contact switch 2055, and the equipment maintains normal spinning operation. When the yarn breaks, the wire ring stops rotating, the tilting block 2057 can no longer push the contact block 2056, the contact block 2056 resets under the action of the return spring and triggers the contact switch 2055, so that the electromagnetic block 2054 is energized to generate magnetic attraction, and completes the real-time self-detection of yarn breakage. After the electromagnetic block 2054 is energized, it forms a magnetic connection with the moving ring 2052, which drives the moving ring 2052 and the sealing ring 2051 to slide precisely along the surface of the suction tube, so that the suction port corresponding to the breakage position remains open, avoiding equipment failure caused by broken yarn and fly hair scattering and entanglement. During the entire operation of the equipment, as the reciprocating sleeve 204 performs continuous reciprocating motion, the collection box 2131 is simultaneously driven to reciprocate along the axial direction of the roller and the rubber roller. When the collection box 2131 moves with the reciprocating sleeve 204 to the set impurity discharge position, the support block 2138 fixed on the suction tube squeezes and pushes the connecting block 2137, making the connecting block 2137 precisely aligned and connected with the connecting groove on the sealing ring 2051, so that the collection box 2131 is in a negative pressure state. When the cleaning scraper 2132 and cleaning brush 2136 on the top of the collection box 2131 move to the position to be cleaned on the roller and the rubber roller at regular intervals, with the continuous movement of the reciprocating sleeve 204, the cleaning scraper 2132 adheres to the roller surface under the elastic force of the movable spring, scraping and cleaning the cotton lint and fly debris attached to the roller surface. The cleaning brush 2136 simultaneously brushes the surface of the rubber roller, and under the negative pressure state of the collection box 2131, effectively cleans the roller. The system collects clean impurities, thoroughly removing impurities adhering to the surface of the roller to ensure stable yarn drafting accuracy and forming quality. Throughout the operation of the equipment, the driven gear 202 rotates continuously with the transmission gear 201, driving the fixed push block 2135 to rotate synchronously. The push block 2135 intermittently pushes the moving block 2134, causing the push ring 2133 to rotate intermittently. Combined with the negative pressure environment inside the collection box 2131, the cleaned impurities are stably collected inside the collection box 2131, preventing secondary dispersion of impurities. The impurities stored in the collection box 2131 are drawn into the sealing ring 2051 through the hose under the action of negative pressure suction, and finally enter the suction tube for centralized processing. When the connecting block 2137 is released from the pressure of the support block 2138, it automatically resets and disconnects the passage under the elastic force of the reset telescopic column, preventing the negative pressure suction of the suction tube from dispersing and ensuring the continuous and stable core adsorption effect.

[0024] In summary, the working principle of this invention fully reuses the transmission power of the original rollers of the spinning machine, eliminating the need for numerous additional independent drive sources. It uses the meshing transmission of the transmission gear 201 and the driven gear 202 as its power basis, with the continuous reciprocating motion of the reciprocating sleeve 204 as its core. Synchronously, the energy storage and cleaning mechanism 2, the negative pressure adjustment component 205, and the moving cleaning component 213 work together. Through negative pressure energy storage throughout the spinning process, the operating logic of triggering spindle rod cleaning upon machine stoppage completely solves the core pain point of traditional spinning machines where yarn tails accumulate and become entangled, requiring time-consuming, labor-intensive, and incomplete manual cleaning. Simultaneously, the alternating opening and closing adjustment of the suction tube's suction port by the sealing ring 2051 achieves total suction of the negative pressure device. The enhanced local adsorption force under the premise of constant adhesion ensures continuous and stable operation of the spinning process. Furthermore, the collection box 2131 moves synchronously with the reciprocating sleeve 204, enabling full-process follow-up cleaning of the rollers and skin rollers. Combined with the negative pressure environment, it completes the closed-loop collection and centralized treatment of cleaning impurities throughout the entire process, avoiding the adverse effects of impurity accumulation on yarn drafting accuracy and forming quality. The matching leaf spring cradle structure, through a stable welded connection, ensures uniform and stable pressure during the yarn drafting process, further improving the quality of the finished spinning product. The overall mechanism has precise timing matching of actions, and the various process links work together, which significantly reduces the intensity of manual labor while effectively improving the operational stability of the spinning machine.
